The invention relates to method of forming a stretchable electrode comprising depositing a metal on the non-fully cured sample via thermal evaporation to form the stretchable electrode. The non-fully cured sample may be uncured or is partially cured for a duration of less than 30 minutes and may be fully cured during deposition of the metal. The invention also relates to a stretchable electrode comprising a base layer； a wrinkled layer； and a plurality of pillars extending from the base layer to the wrinkled layer； and a metal film on the wrinkled layer； wherein the base layer, the wrinkled layer, and the plurality of pillars comprise a polymer.
